[0060] The technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0061] The embodiments of the present application provide a communication method, device and system. The communication device can be integrated in a terminal device, which can be a first mobile terminal or a second mobile terminal. When the first mobile terminal is a drone, the second mobile terminal can be a vehicle control terminal, a vehicle-mounted communication system, a drone controller (handle, etc.), a smart phone, a tablet computer, a notebook computer, a desktop computer, a smart speaker, a smart watch, etc. The network side device on the vehicle belongs to the control terminal. If the second mobile terminal is a drone, the first mobile terminal can be a vehicle control terminal, a vehicle-mounted communication system, a drone controller (handle, etc.), a smart phone, a tablet computer, a notebook computer, a desktop computer, a smart speaker, a smart watch, etc. The network side device on the vehicle belongs to the control terminal.

[0062] In addition, "multiple" in the embodiments of the present application refers to two or more. "First" and "second" and the like in the embodiments of the present application are used to distinguish the description and cannot be understood as implying relative importance.

[0063] The following will be described in detail respectively. It should be noted that the order of the following embodiments is not limited as the preferred order of the embodiments.

[0064] Please refer to FIG. 1, which is a flowchart of a communication method provided by an embodiment of the present application. The communication method is applied to a first mobile terminal, the first mobile terminal is in communication connection with a second mobile terminal, in order to facilitate the description, in the embodiments of the present application, the first mobile terminal is taken as a drone, and the second mobile terminal is taken as a control terminal arranged on a vehicle, for description, that is, the communication method can include:

[0065] S101, if the first mobile terminal and the second mobile terminal are in abnormal communication, obtaining the communication information of the communication device of the environment in which the first mobile terminal and / or the second mobile terminal is located.

[0066] It can be understood that in the scenario of the vehicle carrying the drone, if the drone wants to take off and automatically track the vehicle, it needs to be able to establish stable communication with the vehicle, that is, the drone needs to know the real-time positioning information of the vehicle or the control terminal on the vehicle for controlling the drone, so that the drone can realize the function of following the vehicle, and accurately send its own terminal information, or multimedia data such as pictures or videos taken by the drone, to the control terminal arranged on the vehicle.

[0067] It should be noted that the drone and / or the vehicle can be positioned by WIFI positioning technology. The WIFI positioning is a technology for positioning by using the strength of WIFI signals, that is, when a device is connected to a WIFI network, the device will record the information of the currently connected WIFI network, including the name (SSID) of the network and the signal strength, and the device scans the nearby WIFI signals to obtain the signal strengths of multiple different WIFI networks, so as to estimate the position of the device relative to these WIFI networks according to the differences in the signal strengths of these different WIFI networks.

[0068] Therefore, since the WIFI positioning technology can train a model according to the relationship between the known position and the signal strength of the corresponding WIFI network, and then perform positioning calculation by measuring the current WIFI signal strength of the device using the trained model. The model can be established by using the training data of the known position and the signal strength of the corresponding WIFI network, and modeled by machine learning algorithm, so as to improve the accuracy of positioning.

[0069] Specifically, since each wireless AP (router) has a globally unique MAC address, and generally the wireless AP will not move within a certain time, the positioning calculation can be performed based on the AP signal of the wireless AP, that is, in the scenario where the unmanned aerial vehicle opens the Wi-Fi function, it can scan and collect at least one AP signal around it, so as to obtain the MAC address broadcasted by each AP signal, wherein the AP signal scanned by the unmanned aerial vehicle does not matter whether it is encrypted, whether it is connected, or even the signal strength is insufficient to be displayed in the wireless signal list, which does not affect its use for calculating the position of the unmanned aerial vehicle.

[0070] Then, the unmanned aerial vehicle can send the data related to each AP signal to a location server, so that the location server can retrieve the geographical position corresponding to each AP signal and the signal strength corresponding to each AP signal, and then calculate the position information of the unmanned aerial vehicle based on the geographical position corresponding to each AP signal and the signal strength corresponding to each AP signal, to feed back the position information of the unmanned aerial vehicle to the unmanned aerial vehicle. The location service provider will continuously update and supplement its own database on the location server to ensure the accuracy of the data.

[0071] Therefore, in the embodiment, when the unmanned aerial vehicle and the vehicle obtain their position information, they can send their position information to each other, so that the unmanned aerial vehicle can realize the follow-up function of the vehicle and ensure that the unmanned aerial vehicle can realize real-time communication with the control terminal arranged on the vehicle.

[0072] However, the existing WIFI positioning technology has certain limitations, that is, generally it needs a wireless AP with a relatively fixed position, and a location server to calculate the position of the device to which the wireless AP belongs, so as to realize the follow-up of the unmanned aerial vehicle to the vehicle. However, due to the high-speed movement of the vehicle, the position of the wireless AP cannot be fixed, and it cannot be guaranteed that there will be a location server to provide services, and when the vehicle travels to a place with weak signal, such as a tunnel, an underground parking lot, etc., the positioning information of the vehicle cannot be sent to the unmanned aerial vehicle in time, so that the communication between the unmanned aerial vehicle and the vehicle is abnormal, which leads to the disconnection of the unmanned aerial vehicle, and the unmanned aerial vehicle often deviates from the heading direction and stops.

[0073] Therefore, in the embodiment, when the first mobile terminal detects that it is currently in abnormal communication with the second mobile terminal, in order to reduce the abnormal situation that the unmanned aerial vehicle deviates from the heading direction and stops, the first mobile terminal can obtain the communication information of the communication device in the environment where the first mobile terminal and / or the second mobile terminal is located, so as to establish an association with the communication device through the communication information, to alleviate the disconnection of the unmanned aerial vehicle,

[0074] The communication device includes, but is not limited to, a location server, an LTE / NR base station, a WIFI device, a road side unit (RSU), and the like. The LTE base station is a base station of long-term evolution, and the NR base station is a base station of new radio, which is a 5G communication technology.

[0075] Due to the difference of the communication device, the adapted signal is also different. For example, the base station can use WIFI signals, V2X signals, UWB, and the like.

[0076] The communication information of the communication device includes, but is not limited to, a combination of at least one of the following: identity information, location information, a working frequency band, a transceiving signal power index, and a transceiving signal access criterion of the communication device. The identity information can be an identity ID, a MAC address, and the like. The MAC address is a media access control address, which is an address for uniquely identifying a device in a local area network. The location information can include a corresponding location value obtained from at least one of the following: longitude, latitude, and altitude. The specific setting can be determined according to requirements, which is not limited herein.

[0077] The communication device in the environment of the first mobile terminal and / or the second mobile terminal can be understood as a communication device within a preset range centered on the first mobile terminal, and / or a communication device within a preset range centered on the second mobile terminal. Alternatively, the communication device can be a communication device adjacent to the first mobile terminal and / or the second mobile terminal.

[0078] It can be understood that, due to the different means of obtaining the communication information of the communication device in the environment of the first mobile terminal and / or the second mobile terminal, the obtained communication devices are different. The specific setting can be determined according to requirements, which is not limited herein.

[0079] In some embodiments of the present application, if the first mobile terminal and the second mobile terminal communicate abnormally, the drone needs to detect whether it communicates abnormally with the second mobile terminal before obtaining the communication information of the communication device in the environment of the first mobile terminal and / or the second mobile terminal. Specifically, the drone can receive the third information sent by the second mobile terminal when the communication is normal, so as to ensure the confirmation and update of the location information of the drone and the communication system. The third information is information exchanged between the first mobile terminal and the second mobile terminal when the communication is normal.

[0080] The third information includes at least position information of the corresponding mobile terminal, and the third information includes but is not limited to the communication device information and / or third terminal information of the second mobile terminal. If the second mobile terminal is a control terminal arranged on a vehicle, the third terminal information includes at least one of identity information, position information, control information, and attribute information of the second mobile terminal. If the second mobile terminal is a drone according to another embodiment, the third terminal information includes at least one of identity information, position information, multimedia data captured by the drone, and attribute information of the drone.

[0081] The third information can be transmitted according to a preset first information transmission rule, such as periodic transmission, random transmission, periodic transmission within a preset information transmission period, triggered transmission, etc. The specific transmission rule can be set according to requirements, and is not limited herein.

[0082] Specifically, the periodic transmission can be set according to requirements, such as a transmission period of 10 ms.

[0083] Specifically, the periodic transmission within the preset information transmission period can be set according to requirements, such as a transmission period of 10 ms within a preset time period after the drone takes off, and a transmission period of 100 ms after the preset time period is exceeded.

[0084] Specifically, the triggered transmission is a specific trigger condition preset in the control terminal, so that the information is transmitted after the trigger condition is triggered, or the transmission period of the information is changed after the trigger condition is triggered, such as shortening the transmission period of the information when the trigger condition is that the vehicle speed meets a preset speed, or adjusting the transmission period of the information when the signal quality (SNR, BLER) reaches a certain threshold.

[0085] Correspondingly, while the drone receives the third information transmitted by the second mobile terminal when the communication is normal, the information reception condition of the third information can also be determined to judge the information reception condition of the third information based on a preset abnormal reception condition, so as to determine whether the first mobile terminal and the second mobile terminal are abnormal in communication, i.e. if the information reception condition of the third information meets the preset abnormal reception condition, it is determined that the first mobile terminal and the second mobile terminal are abnormal in communication; and if the information reception condition of the third information does not meet the preset abnormal reception condition, it is determined that the first mobile terminal and the second mobile terminal are normal in communication.

[0086] It can be understood that, since the first information sending rule followed by the control terminal when sending the third information is different, the abnormal receiving condition for judging the information receiving condition of the third information is also different, which can be a condition matched with the first information sending rule followed by the control terminal when sending the third information.

[0087] Specifically, the abnormal receiving condition can include at least one of the following: the third information is not received within a first preset time, the number of times of not receiving the third information meets a first preset number threshold, and the number of times of not receiving the third information within a second preset time meets a second preset number threshold.

[0088] The first preset time and the second preset time can be fixed preset values predefined by a protocol or preconfigured by a base station, or can be a period value of a certain reference signal, or a multiple of a certain reference signal period (the multiple can be predefined by a protocol or configured), and the like, which can be set according to requirements and is not limited herein.

[0089] The first preset number threshold and the second preset number threshold can be fixed preset values predefined by a protocol or preconfigured by a base station.

[0090] In some embodiments of the present application, the third information can include the communication device information, and the communication device information includes the communication information of the communication device in the environment of the first mobile terminal and / or the second mobile terminal. Therefore, the communication information of the communication device in the environment of the first mobile terminal and / or the second mobile terminal can be obtained by the UAV from the third information, so that the UAV can directly obtain the communication information of the corresponding communication device from the control terminal, so as to facilitate subsequent data interaction based on the communication information of the corresponding communication device.

[0091] In some embodiments of the present application, the first mobile terminal is a UAV, and the second mobile terminal is a control terminal arranged on a vehicle, or the first mobile terminal is a control terminal arranged on a vehicle, and the second mobile terminal is a UAV.

[0092] S102, based on the communication information, the first information is sent to the communication device, so that the second mobile terminal obtains the first terminal information of the first mobile terminal from the communication device receiving the first information, and sends the second information to the first mobile terminal based on the first terminal information.

[0093] It can be understood that, due to the abnormal communication between the UAV and the vehicle, in order to avoid the UAV from losing connection, and thus deviating from the flight path, stalling and other abnormal situations, in the embodiment, when the UAV judges that the communication between the first mobile terminal and the second mobile terminal is abnormal, the UAV can send first information to the communication device based on the communication information about the communication device obtained by the UAV, so that the communication device can learn the current situation of the UAV, and feedback to the UAV when necessary, and the UAV continuously sends the first information during the driving process, so as to timely spread the current situation of the UAV.

[0094] The first information includes at least one of first terminal information, multimedia data photographed by the UAV, etc., the first terminal information includes at least one of identity information, position information, terminal communication information, etc., of the first mobile terminal, the terminal communication information of the first mobile terminal includes at least one of modulation and coding mode, data priority, etc., the identity information can be an identity ID, a MAC address, etc., and the position information can include at least one of longitude, latitude, and altitude.

[0095] Specifically, the UAV can send the first information in the form of broadcasting, and the first mobile terminal can send the first information according to a preset second information sending rule, such as periodic sending, random sending, periodic sending within a preset information sending period, triggered sending, etc., which can be set according to requirements.

[0096] In some embodiments of the present application, the communication information includes information related to the communication mode, such as the working frequency band of the communication device, the transceiving signal power index, and the transceiving signal access criterion, etc., so that the first mobile terminal needs to limit the generation of the first information in order to facilitate the communication device to receive and identify the first information.

[0097] Specifically, the communication information can include a working frequency band of the communication device, and the sending of the first information to the communication device based on the communication information can include: the UAV can generate the first information for broadcasting based on the working frequency band in the communication information, or generate the first information for broadcasting based on the working frequency band in the communication information and the working frequency band of the second mobile terminal, wherein the first terminal information in the first information at least includes the identity information and the location information of the first mobile terminal; the first information is sent in a broadcast form, so as to prompt the device belonging to the communication information to receive the first information, or prompt the device belonging to the communication information and / or the second mobile terminal to receive the first information.

[0098] In some embodiments of the present application, the communication device receiving the first information also sends the first information to other communication devices, so as to expand the transmission range of the first information, and enable other communication devices to receive the first information, wherein the communication device can send the first information in a broadcast form, and the communication device can send the first information in a preset second information sending rule, such as periodic sending, random sending, periodic sending in a preset information sending period, triggered sending, etc., which can be set according to requirements, and is not limited herein.

[0099] In some embodiments of the present application, the communication device further includes at least two first communication devices in a preset type of environment, and the second communication device at the exit of the environment is included in the first communication devices, and the second communication device is configured to send location prediction information to the second mobile terminal when receiving the information that the second mobile terminal enters the environment sent by other communication devices in the first communication devices, and the location prediction information is used to predict the location of the second mobile terminal.

[0100] It can be understood that in some special environments, such as tunnels, although the vehicle signal can be weak in these special environments, since there are generally exits and entrances, the characteristics of these special environments can be used to assist the UAV to perform corresponding operations, and the special environment is the preset type of environment.

[0101] And, in the environment, there can be at least two communication devices, i.e. the first communication device mentioned above, respectively arranged at different positions in the environment, and the communication device located at the exit of the environment as the second communication device, so that when the vehicle enters the environment, the communication devices can transmit signals between them in addition to transmitting the information of the communication devices in the environment to the UAV, i.e. the communication device located at the entrance of the environment can broadcast the information of the second mobile terminal entering the environment obtained by the second mobile terminal sending or self-detecting to the communication devices in the adjacent or surrounding preset range, so that the communication devices receiving the broadcast information continue to broadcast until the second communication device receives the broadcast information, and it is clear that the second mobile terminal can pass through the position where the second communication device is located, at this time, if the second communication device receives the first information sent by the first mobile terminal, or receives the information about the first mobile terminal associated with the second mobile terminal sent by other communication devices (which can be the first mobile terminal information associated with the second mobile terminal and the information of the second mobile terminal entering the environment sent by the second mobile terminal to the communication device located at the entrance of the environment at the same time, so that the communication device transmits this time), it can send position prediction information to the first mobile terminal to inform the first mobile terminal that the vehicle will go out from the position, so as to prompt the UAV to decide its subsequent operation, such as the moving path of the UAV, etc.

[0102] For example, there are communication device A and communication device B at the exit and entrance of the tunnel respectively, the vehicle informs the UAV of the relevant information of communication device A and communication device B at the entrance, and communication device A interacts with communication device B after determining that the vehicle enters the tunnel, informs communication device B that the vehicle enters, and can connect with communication device B at subsequent time.

[0103] Among them, the above-mentioned position prediction information is used to predict the position of the vehicle to pass through in the future, such as the position of the exit of the preset type of environment.

[0104] Correspondingly, when the second communication device establishes a link with the second mobile terminal, if the second communication device has received the first information sent by the first mobile terminal, the second communication device can send the first information to the second mobile terminal, and / or if the second communication device has obtained the information of the second mobile terminal entering the above-mentioned environment and the relevant information of the first mobile terminal sent by other communication devices together with the information, the second communication device can generate vehicle positioning information and send the vehicle positioning information to the UAV to prompt the UAV to quickly connect with the vehicle.

[0105] It can be understood that, due to the existence of the preset type of environment, after the UAV obtains the position prediction information, it can scan and detect the information in the area matching the position prediction information according to the position prediction information until the information sent by the second mobile terminal is detected.

[0106] S103, if the second information sent by the second mobile terminal is received, data interaction is performed with the second mobile terminal based on the second information.

[0107] In the embodiment, if the second information sent by the second mobile terminal is received, the unmanned aerial vehicle can establish a communication connection with the second mobile terminal to perform data interaction, so that the unmanned aerial vehicle can normally operate when the position information of the vehicle is lost, and timely communication can be performed in the first time of signal recovery. In addition, since the unmanned aerial vehicle has established a communication connection with the second mobile terminal, the first information can be cancelled, or in order to avoid unstable signals and disconnection, the first information can still be sent within a preset time period after the unmanned aerial vehicle has established a communication connection with the second mobile terminal.

[0108] The second information can be the same as the third information or different from the third information, and the second information includes but is not limited to the communication device information and / or third terminal information of the second mobile terminal. If the second mobile terminal is a control terminal arranged on the vehicle, the third terminal information includes at least one of identity information, position information, control information, and attribute information of the second mobile terminal. If the second mobile terminal is an unmanned aerial vehicle according to another embodiment, the third terminal information includes at least one of identity information, position information, multimedia data captured by the unmanned aerial vehicle, and attribute information of the unmanned aerial vehicle.

[0109] In some embodiments of the application, the unmanned aerial vehicle can control the first mobile terminal to continue moving along the moving path before the communication abnormality after the communication abnormality between the first mobile terminal and the second mobile terminal. After receiving the second information sent by the second mobile terminal, the unmanned aerial vehicle can obtain control information from the second information and control the movement of the first mobile terminal based on the control information.

[0110] In some embodiments of the application, based on the above description, in the embodiment, a timing diagram of a communication method is provided, as shown in FIG. 2, which includes an unmanned aerial vehicle, a control terminal, and a communication device. When the unmanned aerial vehicle and the control terminal normally communicate, the unmanned aerial vehicle can receive third information sent by the control terminal, perform corresponding operations based on the third information, determine information receiving conditions of the third information, and determine whether communication is abnormal based on the information receiving conditions. If it is determined that the unmanned aerial vehicle and the control terminal are in communication abnormality based on the information receiving conditions of the third information, the communication information of the communication device in the environment where the unmanned aerial vehicle and / or the control terminal is located is obtained, and the first information is sent to the communication device based on the communication information, so that the communication device receives the first information and sends the first information to other communication devices.

[0111] The control terminal continuously communicates to obtain first terminal information of the first mobile terminal from the first information obtained by the communication device, and after successfully obtaining the first terminal information, sends second information to the unmanned aerial vehicle based on the first terminal information. The unmanned aerial vehicle can receive the second information to interact with the second mobile terminal based on the second information.

[0112] As can be seen, by applying to the first mobile terminal, the first mobile terminal is in communication connection with the second mobile terminal. If the first mobile terminal and the second mobile terminal communicate abnormally, the communication information of the communication device in the environment where the first mobile terminal and / or the second mobile terminal is located is obtained. Then, the first information is sent to the communication device based on the communication information, so that the second mobile terminal obtains the first terminal information of the first mobile terminal from the communication device receiving the first information, and sends the second information to the first mobile terminal based on the first terminal information. Finally, if the second information sent by the second mobile terminal is received, data interaction is performed with the second mobile terminal based on the second information. When the vehicle and the unmanned aerial vehicle communicate abnormally, data interaction is performed through the communication device located around the two, so that the communication is restored in time and the data interaction is continued when the vehicle and the unmanned aerial vehicle can communicate, and the situation that the unmanned aerial vehicle is abnormal when the vehicle cannot send its positioning information to the unmanned aerial vehicle in time is reduced.

[0113] Please refer to FIG. 3, which is a flowchart of a communication method provided by an embodiment of the present application. The communication method is applied to a second mobile terminal, the first mobile terminal is in communication connection with the second mobile terminal, and in order to facilitate description, the second mobile terminal is taken as a control terminal arranged on a vehicle, and the first mobile terminal is taken as an unmanned aerial vehicle for description. That is, the communication method can include:

[0114] S301, if the first mobile terminal and the second mobile terminal communicate abnormally, the first terminal information of the first mobile terminal is obtained from the communication device in the environment where the second mobile terminal is located.

[0115] In this embodiment, when the control terminal determines that it communicates abnormally with the unmanned aerial vehicle, the control terminal can continue to communicate to receive information sent by different communication devices, so as to determine whether there is first terminal information of the unmanned aerial vehicle or first terminal information related to the position of the unmanned aerial vehicle.

[0116] The control terminal can determine whether there is communication abnormality based on the signal feedback of the unmanned aerial vehicle, such as not receiving the feedback signal of the unmanned aerial vehicle within a preset time length, such as the number of times of not receiving the feedback signal of the unmanned aerial vehicle meeting a preset number, such as the number of times of not receiving the feedback signal of the unmanned aerial vehicle within a preset time length meeting a preset number, etc. The specific setting can be made according to the demand, which is not limited here.

[0117] In some embodiments of the present application, the communication device can include a mobile terminal, which can include a first mobile terminal, so that the control terminal obtains information directly from the UAV, thereby accelerating the communication connection between the two.

[0118] S302, if the first terminal information is successfully obtained, the second information is sent to the first mobile terminal based on the first terminal information, so that the first terminal interacts with the second mobile terminal based on the second information.

[0119] In this embodiment, when the control terminal successfully obtains the first terminal information, it can send the second information to the UAV based on the first terminal information. The UAV can restore the communication connection with the control terminal to interact with data, so that the vehicle communicates with the UAV in time in the first time of restoring the signal.

[0120] As can be seen from the above, by applying to the second mobile terminal, the first mobile terminal and the second mobile terminal are in communication connection. If the first mobile terminal and the second mobile terminal communicate abnormally, the first terminal information of the first mobile terminal is obtained from the communication device in the environment of the second mobile terminal. If the first terminal information is successfully obtained, the second information is sent to the first mobile terminal based on the first terminal information, so that the first terminal interacts with the second mobile terminal based on the second information. When the vehicle and the UAV communicate abnormally, the communication device around them interacts with data, so that the vehicle and the UAV can communicate in time to restore the communication and continue to interact with data, thereby reducing the abnormal situation of the UAV when the vehicle cannot send its positioning information to the UAV in time.
